NEW YORK (CNNMoney.com) - Tax rebates are the centerpiece of the government's plan to stimulate the economy, but many Americans are planning to put the money in the bank or use it to pay off debt, according to a survey released Monday.

A CNN/Opinion Research Corp. poll found that 41% of respondents plan to use their rebates to pay off bills, and 32% will put the money in savings. Just 21% of those polled intend to spend the money, while 3% said they will donate the extra money to charity.

PHILADELPHIA (CNN) - Hillary Clinton began a speech on the housing crisis here Monday by acknowledging the 4,000th U.S. fatality in Iraq, a milestone that occurred yesterday when four American soldiers were killed by an I.E.D. in southern Baghdad.

"I want to take a moment to note yesterday's heartbreaking news that five years after start of war there have been 4,000 U.S. military deaths in Iraq," she said.

"Tens of thousand of our brave men and women have also suffered serious wounds, both visible and invisible to their bodies, their minds and their hearts. As president, I intend to honor their extraordinary service and sacrifice of them and their and their families by ending this war and brining them home quickly and responsibility as possible."

In a statement sent to reporters, Clinton's rival Barack Obama said that, "It is with great sadness that we have reached another grim milestone in Iraq, with at least 4,000 of our finest Americans having been killed."

"Each death is a tragedy, and we honor every fallen American and send our thoughts and prayers to their families. It is past time to end this war that should never have been waged by bringing our troops home, and finally pushing Iraq's leaders to take responsibility for their future ... "

Kilpatrick, who is married, has been snarled in a well-publicized sex scandal since January after The Detroit Free Press reported he exchanged romantic text messages with his then-chief of staff, Christine Beatty.

The newspaper report contradicted testimony Kilpatrick gave in a court case brought by police officers against the mayor and the city of Detroit for misconduct in the mayor's office. The case alleged the mayor retaliated against the officers for their role in investigating his office. Critics alleged that Kilpatrick committed perjury and called for his resignation.

Prosecutor Kym Worthy said that "even children understand that lying is wrong. Witnesses must give truthful testimony."

Worthy said she will seek perjury, official misconduct and obstruction of justice charges.

Kevorkian says he's running for Congress, according to the Associated Press.

SOUTHFIELD, Michigan (CNN) - Less than a year after he was released on parole from a Michigan prison for second-degree murder, assisted suicide advocate Jack Kevorkian announced Monday he is running for U.S. Congress.

Kevorkian, 79, will challenge Rep. Joe Knollenberg, a Republican who has represented Michigan's 9th District since 1993.

At a lengthy news conference in suburban Detroit, Michigan, Kevorkian - who is still on parole - voiced his strong opposition to the war in Iraq.

"I am justified in saying that the United states is a criminal nation. We're a bull in the china shop," he said. "We have committed a horrendous international crime."

He also said he would push for legalizing marijuana in some instances, but was vague on whether his support of assisted suicide would be a campaign issue.

Kevorkian was released on parole on June 1 after serving more than eight years of a 10- to 25-year sentence at Lakeford Correctional Facility, a maximum-security prison in Jackson, Michigan.

He was convicted of second-degree murder in the 1998 death of Thomas Youk, 52, of Waterford Township, Michigan. Youk suffered from amyotrophic lateral sclerosis, or ALS, commonly known as Lou Gehrig's disease.

WASHINGTON (CNN) - The Supreme Court has rejected a conservative group's legal fight to air commercials promoting a movie critical of presidential candidate Sen. Hillary Clinton, in a free-speech debate over whether the ads are political in nature.

Citizens United, a Washington-based advocacy organization, had urged the justices to accept the appeal on an expedited basis this spring, in time for the ads to have an impact throughout the election season.

Monday's decision by the high court means the group - if it chooses to air any broadcast ads - must indicate by name its sponsorship and disclose its political donors.

At issue was whether broadcast ads promoting the 90-minute documentary "Hillary: The Movie" are subject to strict campaign finance laws on political advocacy, or are a constitutionally protected form of commercial speech.

Washington Post: McCain, Traveling Along a TightropeThroughout a week-long trip that took him to more than a dozen meetings with leaders in five countries, Sen. John McCain walked a fine line on Iraq and other issues as the all-but-certain Republican nominee confronted perhaps the central dilemma of his presidential campaign - the question of what role Bush and the legacy of the past seven years will play in his campaign for the White House.

NY Times: Clinton Backer Points to Electoral College Votes as New Measure

NY Times: A Present for McCain as the Other Side Fights
Feuding Democrats have handed Senator John McCain the gift of time. How well he uses it may determine his chance to beat them in November. At the moment, Republicans can savor protracted warfare between Senators Hillary Rodham Clinton and Barack Obama. As the Democratic rivals trade attacks, Mr. McCain, already the presumptive Republican nominee, has crept ahead of both in national polls.

(CNN) - Senator Chuck Hagel, R-Nebraska, said on Sunday that he isn’t ready to endorse his good friend and Republican presidential nominee John McCain, citing major disagreements over the Iraq war.

“I’ve obviously got some differences with John on the Iraq war, that’s no secret,” Hagel told ABC’s George Stephanopoulos on "This Week" Sunday. “Certainly doesn’t put me in Obama or Clinton’s camp, but John and I have some pretty fundamental disagreements on the future of foreign policy.”

Hagel, who has been the one of Republican party’s most outspoken critic of the Iraq war, said he’s not sure what McCain meant when the Arizona senator said on the campaign trail that the United States would stay in Iraq for 100 years if necessary.

“I think we've got to look at the reality that we have before us, and we're in a mess right now… The fact is, all of our senior members of this Cabinet have said that we're not going to sign long-term commitments to defend Iraq,” said Hagel.

The senator from Nebraska had briefly contemplated his own White House run last year, but said recently he is now planning to leave politics. "I don't intend to be in the government next year. I don't anticipate it, and I don't look forward to it," said Hagel.
